Solution Overview

Problem

Existing cleaning devices, such as sweeping robots, require manual cleaning of their components after use, which is inconvenient and time-consuming.

Innovation Solution

A washing control method and apparatus that allows a cleaning device to automatically wash its components at a charging pile by controlling the device to enter with a first posture for cleaning and a second posture for charging, utilizing a washing assembly on the pile to perform washing tasks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cleaning device is equipped with automatic washing function, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning device automatically returns to the charging pile and enters washing mode after completing cleaning tasks, enabling self-service cleaning without manual intervention. The control unit automatically switches between cleaning mode and washing mode, making the device serve itself.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning device integrates multiple functions including cleaning, automatic returning to charging pile, and automatic washing. The same device structure performs different functions by switching modes, reducing the need for separate manual cleaning equipment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If the cleaning device performs multiple cleaning tasks, then the productivity is improved, but the loss of time increases due to manual washing

Engineering Contradiction:
ImproveproductivityVSAvoidloss of time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The cleaning device can continuously perform cleaning tasks without interruption for manual washing. After completing a cleaning task, it automatically returns to the charging pile and enters washing mode, then immediately resumes cleaning tasks, maintaining continuous productive action.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The device performs automatic washing as a preliminary action between cleaning tasks. By automatically returning to the charging pile and washing the cleaning assembly before the next cleaning task, it prepares the device for continued productivity without manual intervention.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If the cleaning device is manually washed, then the device complexity is reduced, but the reliability decreases due to battery loss from frequent charging

Engineering Contradiction:
Improvedevice complexityVSAvoidreliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The washing function is merged with the charging pile. The charging pile serves dual purposes: charging the device and washing the cleaning assembly. This combination eliminates the need for separate manual washing operations and ensures the device is ready for use without battery loss interruptions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device automatically returns to the charging pile for washing after cleaning tasks, ensuring the cleaning assembly is maintained without manual intervention. This self-service approach prevents battery loss by integrating washing with the charging process, maintaining reliability.

Inventive Principle:
Principle #25Self-service

AI summary

A washing control method for a cleaning assembly in a cleaning device, comprising: after a cleaning device enters a charging pile at a first posture, controlling a washing assembly on the charging pile to perform a washing task on a cleaning assembly on the cleaning device (S12); if the washing task is the last washing task of a cleaning process, after completing the washing task, controlling the cleaning device to exit the charging pile, and controlling the cleaning device to enter the charging pile at a second posture, wherein the second posture is different from the first posture (S14), so that the cleaning device can automatically wash its cleaning assembly.
